Having read a fair few of the topics here, some similar to mine but not the same I figured I might as well ask around…
I’m having issues with retrologue when playing midi in manually. Sometimes some notes are considerably quieter than others. I thought it might be my (supersaw) synth preset, but I tried a default preset and still got the same result.
For example I might be playing a simple two-note chord melody, and the top notes every now and again will almost vanish - which is interesting because you can still hear them, only very faintly - which one can only assume means it isn’t note stealing. It happens regardless of the polyphony being set at 8 or 128.
 It’s also worth pointing out that it doesn’t seem to be having this problem with MIDI data that has been drawn in; or maybe I’ve just been lucky.
I will try to upload an audio example.
Any help would be wonderful.
